FEED-WATER HEATER.

Specification of Letters Patent.

Patented d my 25, 1 905.

Application filed September 19, 1994. Serial No. 225,036.

To all whom it may concern:

Be it known that we, BENJAMIN E. EAST- nnim and FRANK L. TAPIA, citizens of the U nitcd States, and residents of Montgomery, in the county of Montgomery and State of Alabama, have invented a new and Improved Fced-W'atcr Heater. of which the following is a full. clear, and exact description.

This invention relates to afeed-water heater designed particularly for use with locomotives, but capable for use in other con nections, as will be understood.

Briefly stated, the invention consists in a means for introducing boiler-steam into the feed water between the injector or other means for forcing the feed water and the point of entry of the feed water into the boiler. In the specific example of the invcntion here given this means consists of a pipe loading from the steam-dome to a fitting interposed in the feed-water pipe and having a valve-controlled connection for the said pipe from the steam-dome, so that upon opening the valve of said connection steam is admitted from the dome into the feed-water, serving not only to raise the tem perature thereof, but to accelerate its movement into the boiler.

Reference is to be had to the accompanying drawings, showing the preferred embodiment of our invention, in which drawingslilre charactors of reference indicate like parts in both views, and in which Figure 1 is an elevation of a locomotiveboiler, showing our invention applied; and Fig. 2 is an enlarged section of the fitting for introducing the steam.

In Fig. l, 10 may be taken to illustrate the check-valve through which the feedavatcr is introduced into the boiler, and 11 the injector.

12 indicates a pipe passing from the steamdome and controlled by a globe or other form of a manually-operated valve 14. Said pipe 12 leads to a nipple 15, passing into a fitting or connection 16, which is interposed between the sections 17 of the feed-water pipe directly adjacent to the place of entry of the feedwatcr to the boiler. Said nipple 15 is commanded by a valve 18, the stem 19 whereof is preferably passed rearward into the cab. so that it may be conveniently reached by the enginedriver. The fitting or connection 16 is fitted with a clack-valve 20, which seats against the return movement of the feed-water, said valve being pivoted at the rearward end of the member 21 of said fitting, which extends forwardly and is flanged at 22 toform a seat for the flange 23 of the bearing 24 for the stem of the valve 18, said bearing being threaded at 25 to screw into a threaded opening therefor in the fitting. That portion of the member 21 extending beyond the forward seat for the valve 18 is gurvcd on its upper surface at 27 in correspondence with the upper curved portion 28 of the fitting, thus assisting in the provision of a free channel 29 for the passage of steam to the feed-water to be heated.

In the operation of the device the injector is started and feed-Water is forced through the pipe and into the boiler in the usual manncr. If it is desired to raise the temperature of the feed-water, the valves 14 and 18 should be opened and steam permitted to flow through the pipe 12 into the nipple 15 and fitting or connection 16, there mingling with the feedwater to raise the temperature of the same. It will therefore be observed that owing to the inclined disposition of the nipple 15 wit" respect to the fitting or connection 16, th inclination being toward the boiler'entranc- 10, the steam passing through said'nippli will accelerate the water movement and assist in forcing it into the boiler.

Various changes in the form, proportions, and minor details of our invention may be resorted to at will without departing from thr spirit and scope thereof. Hence we consider ourselves entitled to all such variations as may lie within the terms of our claims.

Having thus described our invention, we claim as new and desire to secure by Letters Patent 1. In a feed-water heater for locomotiveboilers, the combination with a feechwatc" pipe, and means for forcing the feedwa therethrough, of a fitting in communicati with the boiler and said pipe, having there a valve preventing return of the iced-irate and provided with a steam-controlling valvl 2. In a iced-water heater for locomotive boilers, the combination with a feed-water pipe, and means for forcing the feed-water theretln'ough, of a fitting in communication with the boiler and said pipe, having therein a valve preventing return of the feed-water, and provided with a steam-controlling valve, said fitting being also provided with a removable bearing for the stem of said last-named va ve.

In testimonywhereof we have signed our names to this specification in the presence of two subscribing witnesses.
